BALTIMORE — A group of Maryland lawmakers has announced a series of gun control proposals, including one that would ban the possession or sale of assault weapons.

The legislative package, inspired by the massacre last week at a Connecticut elementary school, also includes proposals to add new requirements of gun dealers and new criteria for people seeking a handgun permit and to reduce the maximum capacity for ammunition in a detachable magazine. The legislation would also designate 45 specified firearms as “assault weapons.”

The bills were announced at a news conference in Baltimore on Wednesday by state senators Brian Frosh, Bill Ferguson, Jamie Raskin and Lisa Gladden.

Gov. Martin O’Malley told reporters Tuesday that he also expects his administration to introduce bills to deal with gun violence.
